a world of yes.

if nothing else, you can get coles/kmart/liquorland giftcards for 5% off.

ie: you can buy a $200 coles giftcard for $190 and use it for your supermarket shopping for the fortnight ... do that every fortnight of the year, and you've saved $260 - after paying only $65 for the book.

without even starting on any of the vouchers!
